I GATE.

Application filed June 29, 1926. Serial No. 119,367.

This invention relates to an improved gate construction for publicdriveways, farm entrances, and similar places.

The invention has more specific reference to the type of gate which isprovided with means located at points at a distance from the gate whichserve to permit the gate to be opened or closed without requiring thedriver of the vehicle to alight,'release the latch and manually push orswing the gate open.

Briefly, the present invention has refen ence to a gate structure,including a support upon which a pair of curved tracks are pivotallymounted, these tracks supporting a pair of gate sections through themedium of roller carrier disks, the inner ends of the tracks beingconnected together and normally located in a plane which causes the gatesections to roll by gravity to closing position. moving the innerconnected ends of the tracks to a position for causing the gates to rolloutwardly and away from each other under the influence of gravity,whereby to permit them to assume an open position. The operating meansfor the tracks is manually manipulated on opposite sides of the gatestructure without requiring the driver of a vehicle to alight and openthe gate in the customary manner.

My principal aim is to generally improve upon structures of this classby providing 7 one of comparative simplicity and durability, wherein theparts are novel, are associated in avnovel. manner, and such as toproduce a structurally and patentably clifferent device from similarstructures with which I am familiar.

In the drawings:

Figure 1 is a view looking at one side of the complete structure,showing the gates closed.

Figure 2 is an end elevation of the same.

Referring to the drawings in detail, it will be seen that the mainsupporting structure is designated generally by the referencecharacter 1. There is a pair of vertical standards 2, having brackets 3attheir upper ends. These standards are connected with a central archt,which in turn is connected through themedium of braces 5, with ahorizontal cross piece 6. Supported on the crest of the arch is asubstantially U-shaped member 7 which functions as a guide in the Meansis provided, however, for

manner to be hereinafter made clear. In turn, another U-shaped member 8is carried by the first named member 7 Connected, as at 9, to thebrackets 3 are longitudinally bowed tracks 10, having curved extremities11. The inner ends of these tracks are connected to a pair of relativelyshort links 12. The gate sections are presented by the referencecharacters 18 and let. The upper portions of the gates are connectedwith a pair of rockably mounted carriers 15, which in turn are providedwith rollers 16 mounted upon the tracks. As shown in Figure 2, therollers are of the grooved type, to aid in maintenance upon the tracksand the carriers 15 are of U- shaped form and the free ends of the armsare arched over the peripheral portions of the rollers to provideretainers of the type 1 shown in Figure 2. The gate section 14; isprovided at its bottom with a keeper 17, which serves to maintain thetwo sections in proper alignment and to facilitate their closing in suchalignment. It is obvious with this arrangement, that by lifting up on'the rear end portions of the tracks the outer end portions will swingdownwardly, thus allowing the carriers 15, and the gate sections toroll, by gravity, outwardly away from each other to open position. Asbefore stated, novel, manually operated means are provided for operatingthe tracks in this manner. The means, i are better shown in Figure 2,wherein it will be seen that levers 18 and 19 are provided, these beingpivotally connected at their upper ends to a supporting member, whichincludes a pair of horizontal arms 20 and 21. The arm 20 is connected toa vertical part 22, which is in turn connected to the U-shaped member 8at its top, as illustrated in Figure 2. The arm 21 is also connectedwith this part 22, but is provided with a U-shaped portion 23 toaccommodate the rocking action of the tracks.

Connectedto the intermediate portions of the levers 18 and 19, are wirerods or links 24, which are connected at their upper ends, with avertical arm 25, riveted on the arch of a rocker member 26. Atthis time,it will be seen that the rocker is pivotally connected at 27' to anupright 28 on the supporting frame structure 1, the pivotal connectionsbeing between the center and one end. A link 29 is connected with thelower bar ofv this rocker 26 and is also connected at its lower end asshown better in Figure 1, with the intermediate portions of theaforesaid links 12. This constitutes the connection between the rockerand the tracks. The upper end of this link 29 extends upwardly throughthe U-shaped guide 7, as shown in Figure 2, this preventing sidewobbling of the rocker member. To add to its rigidity in construction, Iprefer to employ braces 30 which are connected at their upper ends tothe U-shaped member 8 and at their outer lower ends to the horizontalsupporting arms and 21.

In practice, the operating levers 18 are disposed at suitable distancesaway from the gate sections so that the driver of the vehicle inapproaching the ate may simply drive up alongslde of one of the dependng levers, catchhold of 1t, and lift it upwardly as represented inFigure 2. Assuming that the driver is approaching the left hand side ofthe structure as shown in Figure 2, and that he has lifted the lever 19to the position shown, it is obvious that this will exert a longitudinalthrust upon the rod 2% and in so doing, it will, through the medium ofthe connection 25, swing the rocker 25 to position. By thus manipulatingthe parts 19 and 24, the rocker 26 will be 'movcdto position justopposite to that shown in Figure 2, and in so doing, it will liftupwardly upon the link 29 and will in turn lift upwardly upon thepivotal connection between the inner ends of the two tracks 10.Assuming, for instance, that the gate sections are in closed position,it is obvious that this will move the tracks to such a position as topermit the gates to roll, by gravity, away from each other to openposition. After passing through the gate opening and reaching the lever18 on the opposite side of the gate structure, the lever will beoperated as shown in Figure 2, will relock the rocker 26 to a reverseposition as here shown, and will swing the inner pivotally connectedends 'of the two tracks downwardly, thus permitting the two gatesections to roll by ravity back to closed position. It will thus e seenthat the gates are open from one side and closed from the other side.The gates are self adjusting and self aligning.

It is believed that by considering the descri tionin connection with thedrawings,

a c ear comprehension of the construction, arrangement of parts, andoperation Wlll 'behad. Therefore, a more lengthy description is thoughtunnecessary.

Minor changes coming within the field of invention claimed may beresorted to if desired.
